This is an awesome app. Makes it much easier to text my wife while at work if I need to. I'm not a very quick one-finger texter, so being able to use this on the computer is a huge time-saver. And, like someone else mentioned, the only reason I had Chrome installed was so that I could use this on the computer. Now, since I've found the Firefox add-on, I can trash Chrome again. Well worth the registration fee.
